including drivin and driven elements one of whizh is shittableI into andout ol en-f ga'gement with the other land means for shiftingsa-idshiftable element at will. lt also includes a holding means orlatch for holding the movable .pressing member in a down or closedposition and arranged to be loperated by the power actuated means, and

means for releasing the holding means.

The actuating means further comprises mechanism by whichthe movablemember may be caused to vibrate to partly open and close the press andthus alternately and momentarily close the press to apply' pressure andmomentarily partly open the press to slightly separate the pressingmembers so that the vibrating movement causes the movable pressingmember to pound on the gar- 4 -ment and also cause a slight alternatesucking and blowing eliect, all to remove steam and moisture Afrom thegarment, or other article being ressed.

The invention is here shown as embodied in a pressing machine of thetype shown -in patents to A. C. Austin, 'No 1,252,988, J an. 8, 1918,and No. 1,335,151, patented March 30, 1920, inwhich an upperpressing/head is movable toward and from the lower bed or buck mountedon a. suitable frame.

1 designates the frame which may be of 'any suitable form, size andconstruction. The one here shown, includes a suitable table 2 mountedupon front and rear legs 3,-

4, there being two front legs 3 and a single rear leg 4,.the'se legs areconnected by suit? able braces 5. 6 designates the lower pressingelement or bu k which is mounted upon a standard or w at is ordinarilycalled a A goose-neck 6a which in turn' is mounted upon the table .2. 7is the upper .pressingfmemberor pressing head, which is carried by aframe lever Spivoted between its ends at 9 to the upward extension orbracket 10 of the rear leg 4, the rear' arm of the lever carrying acounterbalance weight 10 and being pivoted'at 11 to -one end of thetoggle link` 12,y the other end of which is pivoted at 13 to the upperend of a second toggle link la. 'lhis toggle link 11i in the embodimentof the machine here illustrated is pivoted at 15 iat its lower end tothe frame and is provided with aforwardly extending arm or lever 16rigid therewith and which when operated, tends to,a straighten thetoggle links 12 and 14, and bring the upper gagement with a shoulder 19on the framex and the latch is released by tripping means as a lever 19apivoted to the frame and when depressedl operating to disengage thelatch 17 from the shoulder 19 and permit the weight 10 and also anadditional counterbalancing spring 20to open the pressor elevate thepressing head 7. The pressing head 7 and lower buck 6 are usuallyhollowand heated by steam in any suitable manner, lunnecessary todescribe herein, as steam systems for this purpose are well understoodby-those skilled in the art.

In addition, the machine is provided with the means for permitting steamto .pass from one of the pressing members 5i or 7 usually the lower buck5, through the garment or` article being pressed. This means comprises avalve located within a suitable casing 21,

which casing is in communication with the steam system, and means foropening the valve, as a rod 22 connected at its upper end to the valveand at its lowerend to any well known operating mechanism.

The frame lever 8 whichcarries the. press head- 7 is also provided witha suitable handle 25 by which it may if desired be moved by hand towardpressing position preliminary to the application of final or heavy.pressure by the operator'or by power on the pedal 16. l

`The power operated means for operating.' -the movable pressing member,that is, the

upper pressing head 7 is preferably arranged to apply the final or heavypressure by moving the toggle links into or about the dead i center lineof the toggle after the pressing member 7 has been moved preliminarilytoward the lower buck 5 and the toggle composed of/the links 12, 14 arenot quite in aA v straight or dead center line. However, the

v'power operated means may effect both ythe.

reliminary and final pressure movement,

ut for what might lbe ,called safety first reasons, it is preferabletoeffect the preliminary movement of the pressing head 7 by operatedactuated means that is, hand or foot operated means rather than whollyby member, a driving element mounted on and rotatable with the shaft anda. driven ele- The drive shaft 26 is here illustrated as a shaft drivenby an electric motor 27 mounted on the frame, this shaft beingjournalled 1n suitable bearings formed on the brace 28- extendingbetween one ofthe front and rear legs of the frame, the shaft 26extending transversely of the frame at an angle to'the.

lever 16, and having a worm wheel 29 thereon meshing with the worm 30 onthe armature shaft 31 on the motor, which motor is. also mountedy uponthe brace 28 and secured theretol in any suitable manner. .The motor, ofcourse, is connected in a feed circult which is controlled by anysuitable switch.

As illustrated in Figure 2, the 'driving element is a cam '.32l mountedon the shaft 26 adjacent the lever 16 and theV driven element is afollower 33 carried by the motion transmitting member, as Athe lever 16,and preferably the follower is shiftable laterally into and out of thepath of the constantly rotating cam 32. y

In the illustrated embodiment of our invention, as shown in Figures l, 2and 3, the' follower is mounted `on a rock shaft 34 eX- tendinglengthwise of the motion transmitting member or lever 16 andjournalledin suitable bearings thereon and comprises anv thereon. Aspring 38 is interposedbetween the arm and the lever 16 and tends tonor` mally rock the shaft to carry the follower pin out of the path ofthe'cam 32. A pedal 39 is provided on the front end of the shaft to rockthe sarnecand also to depress the motion transmitting member `or lever16 to preliminarily actuate the toggle links 14 and 12 toward a straightlinecand efl'ect the preliminary movement of the pressing head 7 towardthe lower buck 5:.

In the operation, as thus far described, the operator brings thepressing'-head 7 down toward the lower buck 5 either by pullingdownwardly on the handle 25 or depressing the pedal 3.9 and hencerocking the lever 16 on its ivot 15 and also rocking the shaft and folower 33 against theffaction of the spring 38.

During such preliminary'movement the end of the follower pin 36 abutsthe end face of. the cam 32 and by so doing, limits the roc u" of theshaft so that the pressure apnavarra pressing position andstraighteningthe toggle links and also causing the latch 17 to engagethe shoulder 19 and hence hold the press inits closed position, that is,its position occupied when applying heavy pressure. When the latch 17engages the shoulder 19 as soon as the low point of the cam comesopposite the follower pin, the springv 38 rocks the shaft in the reversedirection and moves the follower pin 36 out of the path of theconstantly rotating cam 32. Hence upon the operation of the trip lever19a to disengage latch 17 from the shoulder 19, the press will be openedby the counter-balancing weight 10. and spring 20. However, it uponrocking of ithe shaft 34 and the depressionof the lever 16 by the 'pedal39, the trip lever 19a is also depres3ed i or held tripped, the roller37 of the follower 36 will be held engaged with the cam 32 by thefriction between the cam and the follower and hence the follower willnot have opportunity to return to its starting position by the spring 38forthe reason that the latch 17 is held from latching with the hook 19by the trip pedal which is being held depressed. Henee, the frictionbetween the cam and the follower is not relieved and as the followerremains in engagement with the cam, successive vibrating movements aretransmitted to the lever 17, toggle links 14, 12, frame lever 8 andupper press head 7 causing the press head 7 to momentarily separateslightly from the lower buck and article thereon and vagain momentarilycome intopressing relation. Hence, the press is alternately opened andclosed, such action continuing until the operator removes his foot fromthe pedal 19EIL and permits the latch to e the shoulder 19. "After thelatch has momentarily engaged the shoulder '19 long enough to permit thespring 38 to.

shift the follower 13 out of the` path of the cam 32, the trip-lever1.9a is again operated to release the latch permitting the press to openfully. llt will be borne in mind that jt-his releasing operation of thefollower is due to the fact that the follower'and cam are 'a slapping orpounding on the garment and also a slight suction and blowing effectwhich e'ectively removes the moisture and steam from the garment. rlhemoisture and steam inthe garment is that injected into the garment bydepressing the lever which opensV the steam valve 21 heretoforedescribed. rlhe slapping flattens lor smooths out the article betterthan continuous pressure.

For the purpo ;:e of adjusting the follower .pin relatively to the cam32 the follower arm is formed with a transverse bearing 40 and thefollower pin-36 is mountedeccentrically in an enlargement 43 mounted inthe bearing 40 and held from turning by a set screw 44. By loosening theset screw 44 and turning the part 43, thefollower pin 36 and rollersthereon can be adjustedtoward and from the working face of the cam.

follower being shiftable, the cam 45`on the constantly movable drivingshaft may be shifted by the operator in the movement of the pressinghead 7 toward pressing position.. ln Figures 5 and 6, the cam 45 isslidably mountedon the driving shaft and Ais actuated by means of theshifter or fork 46 engaging the hub of the cam and actuated throughsuitable connections 47, 48, and spring 49, between the shifter and thelever 16 or some other motion transmitting part.

This connection includes a lever 47 arranged in the path of the lever 16and motion transmitting part 48, between the lever 47 and the shifter46. rllhe lever 47 is here shown as having a head 50 arranged in thepath of the pedalplate 51 on the front end of the lever 16, the platehaving a hole 52 in alinement with the head 50 and through which theheadextends as the lever approaches its down position. ln operation, theoperator places hisfoot on the plate'5-1 and deprefses the lever 16 toeffect the preliminary clos-' ,ing movement of the ypressing member 7.

Toward the end of the preliminary depressing movement the head 50 of thecam shifting lever 47 enters the hole 52, and the foot of theoperatorowhich covers the hole encounters the head 50 and depresses the'lever 470to shift the cam against lthe returning spring 49 during thelatter part of the movement of the lever 47;

Owing to the constantly moving shaft., the operation of the machine issmooth, fast and without jolts and the motor uses a minimum of current.A

rlhe degree of pressure is controlled for each class of work byadjusting the k,toggle in any well known manner.

In the present embodiment'y of our invention, the link 12 comprises athreaded rod, a thrust bearing or end member 54 at the upper end of therod and pivoted at 11 to the frame lever 8 and a lower end member orclevis 55 in which therod is slidable end- As seen in Figures 5 and 6,instead of the l. D

wisely, the end member 55 being pivoted at 13 to the lower toggle link14. The rod of the link 12 is endwisely movable in the end member orclevis 55 relatively to the link 14 and is yieldingly held `from suchendwise movement by a spring 56 encircling the rod of the link 12, andthrusting at one endy against the upper end of the lower end member 5oand at its upper end against an adjusting nut or wheel 57 threaded onthe rod of the link 12 against the upper end of the spring 56. This nutor wheel 57 is locked in its adjusted position by lock nut 58 providedwith a suitable handle 59.

These machines are primarily intended to be used in clothingfactories'and Vlaundries, where the operator works for one period upon acertain class ofwork, all pieces of which require the same amount ofpressure, and therefore, the machine can be readily adjusted to thedesired pressure by adjusting the toggle by turning the wheel 57; andwhen another class of work requiring a dierent pressure is to beoperated on, the pressure can be adjusted for that class of work byturning the wheel 57. I

This power mechanism is particularly advantageous in that it isA readilyand economically applied to standard machines, and further in that owingto the constantly running lmotor, its operation is fast and smooth andis without violent starting and stopping jolts.

Owing to the latch and to the toggle adjustment, the pressure is readilyregulated to a predetermined maximum; and further owing to such powermechanism the garment can be readily dried without additional mechanism,or attachments as blowers, or

vacuum producing attachments.
